Well, the logic is simple...
Mercury's mother has spoken many times about her great relationship with her son. Since Mercury's father hasn't been interviewed about the situation, it's reasonable to assume they had a poor relationship.
See how that works?
And we wonder why they can sell millions of tabloids a day..
Due to a typo by an EMI secretary in 1975, who was actually a small primate (I know! It was the 70's...), the world has until now been unaware that Freddie had a deeply, deeply strained relationship with his father. That's right. It was all right there in Bominian Rhapsody. Thankfully, he had his mama.
Maybe she is sugarcoating, but from the recent interview with Freddie's mom, Freddie's relationship with his dad seemed fine. link
One can only imagine how hard it must have been for Freddie’s devoutly religious parents to come to terms with their firebrand son. Fortunately, the love flowed both ways and Freddie seems to have tried to protect them from his excesses.
Indeed, Mrs Bulsara reveals a very different Freddie to the exotic, bisexual, wild-living, supremely talented performer the public knew. "Freddie kept a strict division between his work and his home all his life," she says.
"If I ever asked he would say, 'Mum that is business, and this is family.’ He was kind and very respectful both to myself and his father."
... "He first had a flat and then a big house, also in Kensington, but when he wasn't away on tour, he would come home regularly... He also invited us for meals prepared by his cook and made a big fuss of me..."
... "After he died my husband and I missed him so much we decided to move to Nottingham, where Kashmira was living with her husband..."
There must have been issues though that maybe a mother could accept but which a father from a very conservative background might really struggle. Anyway, hope they got through anything that arose and their lives were largely happy together while they were both alive.
Lets just be honest anyway. Freddie Mercury made his family rich beyond their wildest dreams. I'm sure he never held much of a grudge when he was driving a nice shiny new car or a bigger house etc.
Freddie's family were already fairly upper-class in their home country, they had servants and didn't have to work. In England they lived fairly normal lives as far as I can see, even when Freddie was famous. So I doubt they concerned themselves much with shiny cars anyway
I thought Freddie's dad worked for the British govt when they were living in Zanzibar. Granted public servant is almost equivalent to doing no work, but still... ;-)
